BACKGROUND OF THE INSTANT DISCLOSURE
[0001] 1. Field of the Instant Disclosure
[0002] The instant disclosure relates to a wiper connector and a
sleeve adaptor; in particular, to a wiper connector connectable to
a bolt-type wiper arm and a sleeve adaptor.
[0003] 2. Description of Related Art
[0004] In recent years, bolt-type wiper arms have been widely
applied in modern cars. Typical bolt-type wiper arms usually have
an engaging structure arranged proximate to the bolt for coupling
the wiper connector. Nevertheless, the bolt-type wiper arms from
different manufacturers across the industry do not share an
universal standard for their engaging structure designs, and
therefore, consumers have to consider if his/her current engaging
structure is suitable before purchasing a new wiper blade. Thus,
bringing disturbances to the consumers in selection of the
products.
[0005] In order to be applicable on the various wiper products,
high adaptability bolt-type wiper arms are being researched and
invented. These bolt-type wiper arms usually have a stopping member
arranged adjacent to the bolt, such that after the bolt is inserted
into the wiper connector at a specific angle, the stopping member
will prevent the wiper connector from detaching during operation.
Although such type of bolt-type wipers are applicable on nearly all
insertion-type wiper products. However, some cars have their own
particularly designed bolt-type wiper arms that do not have the
aforementioned high adaptability. Thus, the designers have to
research new adaptable wiper connectors to meet the demands where
this has turned out to be economically inefficient.
SUMMARY OF THE INSTANT DISCLOSURE
[0006] The object of the instant disclosure is to provide a wiper
connector and a sleeve adaptor thereof for bolt-type wiper arms,

and a second restricting trough connected to the two ends of the
clutching trough, the first and the second flanges of the sleeve
tube are received respectively in the first and the second
restricting troughs, and the tube body is received in the clutching
trough, the tube body is engaged tightly within the clutching
trough.
[0008] The instant disclosure further provides a sleeve adaptor
arranged to a bolt-type wiper arm, comprising a sleeve tube having
a tube body, a first flange and a second flange connected to the
two ends of the tube body, wherein the sleeve tube has a pivoting
hole defined therein and one end of the pivoting hole forms an
opening, the first flange defines a receiving compartment therein;
and a fastening member having a circular ring body and a plurality
of abutting portions protrudingly formed on the inner fringe of the
circular ring body, the fastening member is fixed within the
receiving compartment of the sleeve tube, the bolt is inserted into
the fastening member and the pivoting hole, the circumferential
portion of the bolt is tightly engaged by the plurality of abutting

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] The aforementioned illustrations and following detailed
descriptions are exemplary for the purpose of further explaining
the scope of the instant disclosure. Other objectives and
advantages related to the instant disclosure will be illustrated in
the subsequent descriptions and appended drawings.
The first embodiment
[0031] Please refer to FIGS. 1 and 2, the instant disclosure
provides a sleeve adaptor including a sleeve tube 1 and a fastening
member 2. Preferably, the sleeve tube 1 is a cylindrical structure
made of plastic; however the sleeve tube 1 can also be in the form
of a polygonal prism/column in other embodiments. The sleeve tube 1
has a tube body 11 with a first flange 12 and a second flange 13
respectively extending from the two ends thereof. The outer
diameters of the first flange 12 and the second flange 13 are
greater than that of the tube body 11 to provide a
blocking/positioning effect. The first flange 12 and the second
flange 13 can have different outer diameters. It should be noted
that, the shape and the outer diameter of the tube body 11, the
first flange 12 and the second flange 13 are not restricted thereto
and can be adjusted according to practical needs.
[0032] The sleeve tube 1 has a pivoting hole 14 defined therein,
where the pivoting hole 14 can be a circular hole which is
accommodatable for a bolt 41 of a wiper arm 4. The pivoting hole 14
extends along the axial direction of the sleeve tube 1, and one end
of the pivoting hole 14, referring to the end adjacent to the wiper
arm 4, forms an opening to receive the insertion of the bolt 41 of
a wiper arm 4. The hollow interior inside the first flange 12
defines a receiving compartment 15. The shape of the receiving
compartment 15 corresponds to that of the fastening member 2 in
order to receive the fastening member 2. To provide further
explanations, the other end of the pivoting hole 14, referring to
the end away from the wiper arm 4, can be either closed or opened
to the exterior, where the inner diameter thereof can be smaller
than the diameter of the bolt 41, shown in FIG. 7, to prevent
mis-mating of the bolt 41 into the pivoting hole 14 from this
end.
[0033] Preferably, the fastening member 2 is in the form of a
push-on clip made of metal. For the instant embodiment, the
fastening member 2 has a circular ring body 21, an interfering
portion 22 (outer rim), and a plurality of inwardly extending
abutting portion 23. The circular ring body 21 is preferred to be a
ring-shaped structure having an inner diameter that corresponds to
the bolt 41, where the cross-sectional shape thereof can also be a
polygon and is not restricted thereto. The interfering portion 22
is formed circumferentially around the circular ring body 21, where
the shape and the amount thereof are not restricted thereto. For
the instant embodiment, the interfering portion 22 is substantially
a ring-shaped structure. The plurality of abutting portions 23 is
formed in the inner fringe of the circular ring body 21 and
protrudes therefrom, where the shape and the amount of the abutting
portion 23 are not restricted thereto. For the instant embodiment,
the abutting portion 23 is substantially a trapezoid-shaped
structure, where the abutting portion 23 extends along the same
direction with the inserting direction of the bolt 41. Specifically
speaking, the extension of the abutting portion 23 is in the same
direction with the inserting direction of the bolt 41 to enable
smooth insertion, however difficult extraction, of the bolt 41.
[0034] The fastening member 2 is received in the receiving
compartment 15 of the sleeve tube 1, and is fixed within the
receiving compartment 15 through frictional contact of the
interfering portion 22 to the inner walls of the receiving
compartment 15 (shown in FIGS. 3 and 4). The fastening member 2 can
also be fixed within the receiving compartment 15 of the sleeve
tube 1 by mean of insert molding and other means to form a sleeve
adaptor therewith. To provide further explanation, the distance "a"
(shown in FIG. 1), referring to the distance between the inner and
outer diameters of the fastening member 2, preferably smaller than
5 mm, even better, smaller than 3 mm to provide an ideal fixing
effect, but this is not restricted thereto. However, if the
distance "a" is greater than 5 mm, the strength of the fastening
member 2 may be weakened such that the fixing effect thereof may
also be weakened. Nevertheless, as long as the abutting portion 23
on the inner fringe of the fastening member 2 can abut tightly
against the outer fringe of the bolt 41 will do. To provide further
explanations, the shortest distance formed between the tips of the
abutting portion 23 is shorter than the diameter of the bolt 41. In
other words, the diameter of the circle formed by joining the tips
of the abutting portion 23 is shorter than the diameter of the bolt
41. Also, the size of the sleeve tube 1 and the fastening member 2
is not restricted thereto and can also be adjusted according to
practical needs.
[0035] Please refer to FIGS. 3-7. The sleeve tube 1 and the
fastening member 2 are assembled together before pushing the
assembly of the sleeve tube 1 and the fastening member 2 directly
into the bolt 41 for the bolt 41 to be inserted into the fastening
member 2 and the pivoting hole 14. The circumferential portion of
the bolt 41 will engage tightly against the inner fringe of the
fastening member 2 to achieve a stabilized assembly. The sleeve
adaptor cannot be easily dismantled from the wiper arm 4 after
assemble thereto. Thus, forming a firm structure which cannot be
easily dismantled unless by force to achieve the protecting effect
of the bolt 41. There may be adjustments on the dimension of the
bolt by the manufactures and thereby, the dimension of the sleeve
tube 1 and the fastening member 2 is not restricted thereto and can
be adjusted due to practical needs to be applicable on bolts of
different dimensions.
[0036] The instant disclosure further provides a base 3. By
assembling the base 3 to the sleeve tube 1 and the fastening member
2, a wiper connector can be formed to connect the wiper arm 4 and
the wiper blade, where the structure and the type of the base 3 is
not restricted thereto. For the instant embodiment, preferably, the
base 3 is made of plastic and is integrally formed as a single
unit, however, the base 3 can be also made of detachable
components. The base 3 has a clutching trough 31, a first
restricting trough 32 and a second restricting trough 33 connected
at the two ends of the clutching trough 31, where the structural
design of the clutching trough 31, the first restricting trough 32
and the second restricting trough 33 is not restricted thereto. The
clutching trough 31, the first restricting trough 32 and the second
restricting trough 33 are in correspondence respectively to the
tube body 11, the first flange 12 and the second flange 13, and are
arched troughs having openings on the top portions thereof. The
opening on the top portion of the clutching trough 31 has a width
smaller than the outer diameter of the tube body 11 to clutch and
fix the sleeve tube 1.
[0037] The base 3 can further have an anti-mismating trough 34
formed thereon and at least one accommodating slot. For the instant
embodiment, there are two accommodating slots, namely, a first
accommodating slot 35 and a second accommodating slot 36. The first
accommodating slot 35 and the second accommodating slot 36 may be
arranged in such a way to accommodate the shoulder portion 42 of
the wiper arm 4, thus avoiding structural interference between the
wiper arm 4 and the base 3. For instance, the first accommodating
slot 35 can receive the shoulder portion 42 of the wiper arm 4 to
prevent interference between the base 3 and the shoulder portion
42.
[0038] The structural design of the anti-mismating trough 34 is not
restricted thereto. For the instant embodiment, the anti-mismating
trough 34 includes a protrusion 341 and a protrusion 342
protrudingly formed on the base 3, where the protrusion 341 and the
protrusion 342 are formed on the two sides of the clutching trough
31. The distance "b" formed between the protrusion 341 and the
protrusion 342 of the anti-mismating trough 34 is smaller than the
outer diameter "c" of the first flange 12, the outer diameter "d"
of the second flange 13, and the width "e" (shown in FIGS. 1 and 2)
of the shoulder portion 42 of the wiper arm 4 to provide the
anti-mismating effect. Thus, the sleeve tube 1 can only be
assembled to the base 3 from the top but not in any other direction
to ensure that the sleeve adaptor, the base 3 and the wiper arm 4
are assembled in the correct direction.
[0039] The distance "f" (shown in FIG. 9A) from any edge of the
anti-mismating trough 34 to the center point of the sleeve tube 1
is greater than or equal to the distance "g" from the center point
of the bolt 41 to the shoulder portion 42. Thus, if the sleeve tube
1 and the base 3 are assembled together before the bolt 41 of the
wiper arm 4 is assembled to the sleeve tube 1 and the base 3, the
bolt 41 will be unable to insert thereinto as the distance "f" is
greater than or equal to the distance "g". Therefore, the shoulder
portion 42 of the wiper arm 4 will abut against the anti-mismating
trough 34 to occur interference therebetween during insertion
regardless from any inserting angle. Thus, an anti-misating effect
can be provided since the bolt 41 will not be able to insert into
the sleeve tube 1 and the fastening member 2.
[0040] The width "j" of the anti-mismating trough 34 is greater
than or equal to the distance i formed between the inner fringe of
the shoulder portion 42 to the edge of the bolt 41. Thus, if the
sleeve tube 1 and the base 3 are assembled together before the bolt
41 of the wiper arm 4 is assembled to the sleeve tube 1 and the
base 3, the bolt 41 will be unable to insert thereinto as the width
"j" is greater than or equal to the distance "i". Therefore, the
anti-mismating trough 34 will interfere with the bolt 41 and the
shoulder portion 42 to prevent the bolt 41 from inserting into the
sleeve tube 1 and the fastening member 2, and thereby providing the
anti-mismating effect.
[0041] Please refer to FIGS. 8 and 9. The wiper arm 4 will be
substantially parallel to the base 3 after assembly with the sleeve
adaptor. Specifically speaking, the wiper arm 4 will be above the
base 3 to form an angle .gtoreq.0 therebetween. The wiper arm 4 is
then depressed in the vertical direction for the first flange 12
and the second flange 13 to receive respectively within the first
restricting trough 32 and the second restricting trough 33 of the
base 3, while the tube body 11 is received in the corresponding
clutching trough 31. Therefore, the tube body 11 is tightly engaged
to the clutching trough 31 to be nicely assembled. After the
assembly of the wiper arm 4, the sleeve tube 1 and the base 3, the
inner portion of the wiper arm 4, away from the base portion of the
bolt 41, will not interfere with the base 3.
[0042] Basically, according to the wiper arm 4 shown in FIG. 1, the
bolt 41 does not possess fastening ability; the fastening ability
(or the locking ability) thereof is achieved through the mechanical
interference provided by the shoulder portion 42. Therefore, during
the operation of the wiper, there will be two forces acting on two
different planes, where these two forces may cross-interfere, thus
creating instability. Aside from the bolt-protecting function, the
sleeve adaptor of the instant disclosure may convert the multiple
forces from the wiper arm 4 into one. Therefore, improving the
functional stability of the wiper during operation even in cases
where the shoulder portion 42 of the wiper arm 4 is not in the
locking condition.
Embodiments Two to Seven
[0043] Please refer to FIGS. 10 to 15, the instant disclosure can
be applied on different types of bolt-type wiper arms and is not
restricted only to the wiper arm mentioned in the first embodiment.
The bolt 41 of the bolt-type wiper arm can be selected from the
group consisting of a cylinder (shown in FIG. 10), a triangular
prism (shown in FIG. 11), a tetragonal prism (shown in FIG. 12), a
hexagonal prism (shown in FIG. 13), a polygonal prism (shown in
FIG. 14), and an irregular-shaped prism (shown in FIG. 15) or even
prisms in other shapes, where any type of wiper arm which has bolt
is suitable for the wiper connector and the sleeve adaptor of the
instant disclosure.
[0044] The wiper connector and the sleeve adaptor of the instant
disclosure has the following advantages:
[0045] 1. The wiper connector and the sleeve adaptor of the instant
disclosure cannot be easily dismantled after they are assembled
together, and thereby forming a firm, sleeve adaptor which cannot
be easily dismantled except by force. Therefore, the bolt can be
well protected and the functional stability of the wiper during
operation can be well maintained.
[0046] 2. The wiper arm with the assembled sleeve tube can be
assembled to the base directly from the top, where this assembly
method is different from the methods of the prior art.
[0047] 3. The wiper connector and the sleeve adaptor of the instant
disclosure have simple structures and can be easily assembled, and
thereby, providing advantages such as easy utilization and a lower
cost.
[0048] 4. The base of the instant disclosure can further include a
anti-mismating portion to provide the anti-mismating function, and
thereby reducing the possibility of damaging due to mismating.
[0049] 5. The instant disclosure is widely applicable which can be
applied on different bolt-type wiper arms, therefore, there is no
need to select specific wiper assemblies having bolts in different
forms in order to be connectable.
[0050] The descriptions illustrated supra set forth simply the
preferred embodiments of the instant disclosure; however, the
characteristics of the instant disclosure are by no means
restricted thereto. All changes, alternations, or modifications
conveniently considered by those skilled in the art are deemed to
be encompassed within the scope of the instant disclosure
delineated by the following claims.
